First thing.. Can anyone identify this alternator? Or even if it is an alternator? Iv never really seen a dynamo/generator.
My vehicle - 53' F100 fitted with a 272 Y Block
Trying to follow a few diagrams but iv yet to find a definitive wiring diagram.
The wiring that comes off the alternator/generator to the voltage regulator, then a wire should run from the Bat terminal to the positive side of the battery... Correct
My truck came with a 12v conversion, my intention was to just follow that and replace it with new wiring and new instruments and switches. However as iv delved into it, it's a mess and it's clear whoever did it, had no idea what they were doing and got it to work just about.
Im starting from scratch, it's too basic a system to warrant buying a loom, I will be able to gain help from my friend who's an auto electrician in a few days but any info I gain in the meantime the better.
Measuring the Bat terminal off the voltage regulator, it's only producing 3v on tickover. I know the earth are bad, but that's not going to make that much difference is it.

If you mean the ground is bad, YES that will make a HUGE difference.
From memory, that thin red cable towards the top is the earth and it runs and is sandwiched between the inner fender and voltage reg mounting bolt. To my knowledge the earth for the alternator has always been fairly sizeable?
The two terminals are Armature and Field, neither should be grounded. This is for a 6v generator but 12v should be the same. There will be an "F" and an "A" stamped into the case of the gen next to the appropriate terminal.
That is, indeed, a generator. Generators can work well, but they don't produce much charging current at idle. One of the classic generator problems is that all of the charging current has to pass through the carbon brushes. The brushes don't last all that long accordingly.
If you're in a fabrication mode and feel like spending a little, I would consider a one-wire alternator. Something like this one listed at Summit Racing: http://www.summitracing.com/parts/tff-7068
The Tuff-Stuff alternators have a front body that is like a 1st generation Ford (so 1G). The back half has the Delco body with the GM style diodes sets and regulator.
You would have to fab a bracket, and get rid of the voltage regulator and associated wiring. There are some generic brackets available.
Order'd an 80amp Alternator. Will fit, then fit a fusebox and wire it up like a modern car and have everything fused. Think its best to start from scratch
